Problems solved by technology

[0002] At present, the rotary feeder and the three air lock valves used in the feed device of the domestic dry process cement production line, when the rotary feeder feeds, the material directly impacts the rotor blades, resulting in faster wear of the rotor blades, and even frequent material jams Parking will consume a lot of energy, and the service life will be greatly shortened. In addition, the air locking performance of the three air lock valves is unstable, and maintenance is inconvenient.

Embodiment Construction

[0018] A vertical roller mill rotary feeder, including a base 1 and a reducer motor 2, a rotor 3 and a housing 4 arranged on the base, the reducer motor controls the rotation of the rotor; eight blades 5 are fixed on the outer periphery of the rotor, And a hopper 6 is formed between every two blades; the housing is fixed on the periphery of the blades; the top and bottom of the housing are respectively provided with a feed inlet 7 and a discharge port 8, and the eight blades on the rotor are Eccentric, and the hopper formed by it is also eccentric. In this way, the motor of the reducer drives the rotor and the hoppers on it to rotate, so that different hoppers enter the feed inlet in turn to feed, and then rotate to the outlet to discharge. When a hopper has just been rotated by the rotor and enters the feed port, the material will hit the blade on one side of the rotor at the beginning, but because the hopper is eccentric, the material and the side of the hopper will be in a ...

Abstract

The invention discloses a vertical roller mill rotary feed device, comprising a base and a reducer motor, a rotor and a shell which are arranged on the base, wherein the reducer motor controls the rotor to rotate; the periphery of the rotor is fixedly provided with a plurality of blades, and a hopper is formed between every two blades; the shell is fixedly arranged on the periphery of the blades; the top and the bottom of the shell are respectively provided with a feeding hole and a discharging hole, the blades on the rotor are eccentric, and the formed hoppers are also eccentric. According to the invention, the vertical roller mill rotary feed device has the advantages of simple structure, little abrasion, low energy consumption, long service life, and stable air locking performance.

Description

technical field [0001] The invention relates to a vertical roller mill rotary feeder. Background technique [0002] At present, the rotary feeder and the three air lock valves used in the feed device of the domestic dry process cement production line, when the rotary feeder feeds, the material directly impacts the rotor blades, resulting in faster wear of the rotor blades, and even frequent material jams Parking will consume a lot of energy, and the service life will be greatly shortened. In addition, the air locking performance of the three air lock valves is unstable, and maintenance is inconvenient. Contents of the invention [0003] In order to overcome the above defects, the present invention provides a vertical roller mill rotary feeder, the vertical roller mill rotary feeder not only has a simple structure, less wear, but also low energy consumption, long service life, and stable air lock performance . [0004] The technical solution adopted by the present inventi...
